Title: Improvements in and relating to combined diaphragm horns and lamps
IPC: G08B7/02
Filed: 1920-09-06
Abstract: 168,919. Gratze, E. V. Hayes-. Sept. 6, 1920. Lamps combined with diaphragm horns.-A combined sound alarm and lamp particularly for use on motor road vehicles comprises a streamline shaped casing a with a parabolic reflector b carrying a lamp c mounted concentrically within the mouth of the casing. In rear of the reflector is a diaphragm e mounted against a flange a' of the casing by a screwed ring e<1>. The diaphragm carries a stud e<2> engaged by a ratchet wheel f fixed to a spindle g. The upper bearing for the spindle g is a screw head h' with a socket containing a ball i which also fits in a recess in the upper end of spindle g. A shoulder g<1> on the lower end of the spindle g bears on a bush k passing through a hole in a boss on the casing. The hole in the bush k is drilled eccentrically so that wear between the stud e<2> and the teeth of the ratchet wheel f may be taken up. In a modification a small dynamo is contained in the rear part of the casing a and supplies current to the lamp c, and when required to an electromagnet for vibrating the diaphragm. Or the ratchet wheel for this purpose may be splined to the armature shaft of the dynamo and moved into or out of engagement with the stud on the diaphragm as required.

Abstract: 245,086. Soc. GenÚrale des Compteurs de Voitures (Taximetres). Dec. 29, 1924, [Convention date]. Counting -apparatus. - An intermittently rotated ratchet wheel 10, which may form part of a taximeter or other counting or like apparatus, is positively locked when not being driven, by a detent 12 adapted to be raised during the operative stroke, by the lever carrying the driving pawl 7. The pawl 7 is shown pivoted to the end of a lever 3 controlled by a spring 6 and a continuously rotating cam 2. The locking detent 12 pivoted at 13 and normally drawn into action by a spring 14, carries a pivoted plate or arm 15 drawn by a spring 19 against an adjustable screw stop 18. During the operative stroke, as the pawl 7 comes into action, the end of the lever 3 engages the plate 15 and lifts the detent 12, allowing it however to drop as the lever passes the plate. During the return movement, the spring 19 yields, allowing the plate 15 to rock without disengaging the detent 12. The lift of the detent is regulated by the screw 18.
